Antigravity Agent e9cbf23ab5 docs(10_Wiki): Dev 폴더 누락분 반영 — Topic_Programming으로 통합
이전 재구성 작업에서 Dev/ 폴더가 누락되었던 것을 반영.

- Dev/Topic_Programming(중첩 폴더, 78개)은 Dev 자체 최상위 폴더들
  (Architecture/Conventions/Engineering_Intelligence 등)과 완전 중복이라 제거.
- Dev 최상위 엔지니어링 지식 폴더(Architecture/Conventions/Engineering_Intelligence/
  Failure_Library/Generalized_Principles/Language/Pattern_Catalog/Platform_Guides/
  Subsystems, 77개)는 이미 Topic_Programming/Topic_Programming에 더 최신 버전이
  존재해 중복 제거(고유 콘텐츠 1개는 예외 처리하여 이동 보존).
- Dev의 W3Schools 언어 튜토리얼 폴더(Topic_C/CPP/CSS/CSharp/HOWTO/HTML/Java/
  JavaScript/PHP/Python/SQL/W3CSS, 1201개)는 전부 Topic_Programming 하위로 이동.
- 에이전트 운영 상태(.astra/docs)는 그대로 유지, 콘텐츠 폴더만 정리.
- Topic_Programming 최종 문서 수: 2784 → 3985.

PHP Comments

🎯 한 줄 통찰 (One-line insight)

PHP uniquely supports TWO single-line comment styles (// and #) where most languages offer just one — both are fully interchangeable and equally legal, a flexibility inherited from PHP's C-style (//) and shell-script-style (#) heritage. [S1]

🧠 핵심 개념 (Core concepts)

  • Single-line comments// or #; everything to end-of-line is ignored. [S1]
  • Multi-line comments/* ... */. [S1]
  • Purposes — explain code to others, remind yourself later, temporarily disable code for testing. [S1]
  • Ignoring code via comments — commenting out a line prevents its execution. [S1]

📖 세부 내용 (Details)

  • Two single-line styles: // This is a single-line comment and # This is also a single-line comment. [S1]
  • Comment before code: // Output welcome message echo 'Welcome Home!';. [S1]
  • Comment at line end: echo 'Welcome Home!'; // Output welcome message. [S1]
  • Disabling code: // echo 'Welcome Home!'; — the echo never runs. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 테스트 중 특정 코드 줄을 비활성화하는 용도로 주석이 자주 쓰인다. [S1]

💻 코드 패턴 (Code patterns)

Two equivalent single-line comment styles (PHP):

// This is a single-line comment
# This is also a single-line comment
